Extra large Dubia nymphs make excellent primary feeders for animals that can manage large insects. They have size on their side, but not only that, they have excellent nutrition too. These bad boys contain all the vitamins, minerals, and other beneficial nutritional stuff Dubia roaches are famous for.
At around 2 grams each, 1-½ inch Dubia roaches are large feeders. They’ve been pounding food nonstop for 4 months or so, and they’re almost always in their final instar (growth stage) before adulthood. In fact, a few may even turn into adults between the shipping and the time they reach you. This is as full-grown as Dubia nymphs get, and at this size their exoskeletons are thicker than smaller-sized nymphs. However, they’re very low in chitin relative to other feeder insects, and compared to Dubia adults.
As we’ve said many times before, Dubia are outstanding feeder roaches for many reasons. A big reason is superior gutload-ability, and gut loading is where 1-½ Inch Dubia Roaches stand out. Literally. These guys can pack in an enormous amount of food, and when they do, it’s very easy to tell. Their full stomachs cause significant body elongation, and that bulging belly is the signal that they’re ready for feeding.
And of course, when you combine superior innate nutrition with exceptional gut load-ability, you get a feeder that is difficult if not impossible to beat from a nutritional perspective.
Like all our roach stock, 1-½ Inch Dubia are born and raised on distilled water, fruits and vegetables, and our own roach chow formulation, which contains an abundance of nutrients targeted to support each stage of development. Of course, we feed our organic Dubia organic fruits, vegetables, and feed made from organic ingredients. Our late-stage nymphs are packed with nutrition accumulated over a lifetime of abundant feeding on nutritionally targeted feed.
These roaches can differ a bit in size, and 1-½ inches is about their maximum length. Any variation is usually small – maybe 10% or so. Their size in the moment depends on a variety of things, including hydration and feeding schedule.
